I have a 2001 Silverado 1500 and the 5.3L in it had got a knock with 70,000 miles!!!!! So im tryjn to figure out what motor i should stick in there that will make me happy. Any ideas?

 

6.0, will need a 6.0 PCM

 

with a cam and bolt ons

 

A Silverado f-body?

 

Are you waiting for someone to say "put an LS1 in it!!" ???

Depends on how much time/money you want to spend. Do you want your truck back sooner or later? Do you want it to run with F-bodies (or Lightnings?) or just have a little more grunt? The 5.3L is a fine engine on its own, so why not just rebuild it and put in a different cam while you're at it and call it a day? It would be a lot easier than doing a not-worthwhile swap to a 6.0L or LS1 (IMO) which would require more changes / modifications, considering you're only talking a difference of ~20 to ~30 cubic inches.

BUT, if you've got lots of money to spend, then I'd have to vote for something along the lines of an LS6, or maybe a big cube LSx engine (can anyone say, "427"?) 'cause in a truck, bigger is certainly better! But hey, that's your call.

 

Cool, thanks guys

 

Here's what's in my Silverado

Love that horn! What is it, a PA system?

 

if only you could get the dash in there..........

 

Thats for the alarm and boy is it loud...it scares the crap out of me every time I accidentally set it off

 

No kidding, that would have been killer!
Now if I could get this boat to go with it!

FYI, almost all Gen-3 GM V8's knock, our 4.8L tahoe knocks at times bad! especially when cold! I've heard the same from the 5.3 and 6.0, dont know about the 8.1L

Is it dying or ready to blow up?

 

This problem is SOOOO common there is a class action lawsuit going on against GM about it......

Most people just keep on driving the trucks for another 50,000 miles with no problems. They are just noisy

 

Ive had a couple of people tell me i should just rebuild the motor in it and beef it (the 5.3L) up a bit....BUt eveyone is tellin me somethng different so i cant decide. And wtf is up with no Posi? They just make you put money into these trucks!

 

Yeah, I slipped an Eaton posi unit into my diff for around $500.
